Product Overview
The Specpure® phosphorus plasma standard solution (1000µg/ml) is a high-precision reference material designed for demanding analytical applications where accuracy and traceability are critical. Formulated using ultra-high-purity phosphorus in a stabilized aqueous matrix, this solution eliminates matrix interferences, ensuring consistent performance in ICP-OES, ICP-MS, AAS, and spectrophotometric analyses. The Specpure® grade guarantees minimal trace metal contamination (<1 ppb for most interferents), making it ideal for low-level phosphorus determination in environmental, clinical, or industrial samples. Each batch undergoes rigorous multi-point calibration against NIST-traceable standards, with certification provided for concentration accuracy (±0.5%). The solution’s long-term stability (12+ months when stored at 15–25°C) is achieved through proprietary buffering agents that prevent precipitation or microbial growth. Compatible with most autodilution systems, it reduces preparation time while maintaining linear response across a broad dynamic range (0.01–100 ppm). The amber glass packaging with PTFE-lined caps ensures zero leaching or evaporation, preserving integrity during storage or transport. Whether used for calibration curves, quality control checks, or method validation, this standard delivers reproducible results with minimal lot-to-lot variation, backed by a comprehensive Certificate of Analysis detailing impurity profiles and stability data.
FAQs
1. What is the shelf life of this phosphorus plasma standard solution when unopened?
The unopened solution remains stable for 24 months from the date of manufacture when stored at 15–25°C in its original packaging. Avoid exposure to direct sunlight or temperature fluctuations.
2. Can this standard be used directly for ICP-MS analysis without further dilution?
For most ICP-MS applications, dilution to 1–10 ppm is recommended to avoid detector saturation and matrix effects. The 1000µg/ml concentration serves as a stock for preparing working standards.
3. Is this solution compatible with organic solvents like methanol or acetone?
The aqueous-based formulation is optimized for water-compatible systems. For organic solvent applications, consider evaporating the solution under nitrogen and reconstituting in the desired solvent, though this may affect stability.
4. How does the Specpure® grade differ from standard analytical-grade phosphorus solutions?
Specpure® undergoes additional purification steps to reduce trace metal contaminants (e.g., Fe, Ca, Mg) to sub-ppb levels, ensuring minimal spectral interferences in high-sensitivity techniques like ICP-MS. Standard grades may contain up to 10–50 ppb of such impurities.
5. What documentation is provided with each batch for quality assurance?
Each bottle includes a Certificate of Analysis (CoA) with lot-specific data: exact concentration, expiry date, impurity profile (via ICP-MS), stability test results, and NIST traceability statement. MSDS is available upon request.
